How much time did you learn each day?
I didn’t need to give my whole life over to learning Norwegian. Each Babbel lesson takes only 15 minutes, and I set myself the achievable aim of finishing three Babbel lessons daily. This took 45 minutes each day.
How did the Babbel app help you learn so quickly?
The Babbel app has a course plan for beginners that taught me how to make sentences in Norwegian within the first few days. Then I was able to personalize my learning by choosing single-topic lessons on eating, drinking, music, culture, travelling and so on. This allowed me to quickly enlarge(扩大) my vocabulary!
This way of learning kept me highly active, and made sure I wasn’t bored to tears(眼泪) with grammar practice that we all remember from school!
“After 7 days I was able to introduce myself in Norwegian, talk about my hobbies and interests, and most importantly, communicating with a native(本国的) Norwegian speaker in a real conversation and I could even play a joke or two!”
Would you introduce this app to others?
Certainly! Babbel has 14 languages to choose from, so if you’re thinking about brushing up on your German for a business trip, or learning a bit of Portuguese(葡萄牙语) for next year’s summer vacation, you’ll be happy to hear that you only need an app, 7 days of learning to get you conversational.
1. The Babbel app is used for people to _______.
| A．speak with natives | B．learn foreign languages |
| C．do international business | D．plan a vacation abroad |
| A．It took him little time every day. |
| B．It provided him with 14 languages. |
| C．It gave him daily grammar practice. |
| D．It offered lessons according to his needs. |
| A．hard work matters a lot | B．Babbel app sells well |

Humans are getting away from the nature gradually because of the developing technology. But now Digital Technology is offering us an opportunity to listen to the sounds in the nature in powerful ways, making us get closer to the worlds of animals and plants.
All around the nature, there are sounds that we struggle to pick up and understand. Elephants, for example, communicate with each other using infrasound, a sound far below our human hearing range. Coral in the ocean also communicates with each other through sound waves, with one purpose of attracting baby coral to areas where it can successfully grow. This is a shocking fact as coral doesn’t have any ears!
To pick up sounds humans are normally unable to hear, scientists have placed listening devices in these environments. Researchers have attached tiny microphones to honeybees and turtles, and stuck listening posts that can receive different sound waves from coral reefs and trees. These devices are controlled by computers and networked with digital sensors and satellites. When interconnected, these digital devices work like a hearing aid: enabling humans to observe and record nature’s sounds beyond the limits of our own listening ability. After the sounds are recorded, AI is then able to determine their meanings.
With this technology, humans can not only understand the animals, but also communicate back to them. For example, a team of researchers in Germany decoded the honeybees’ behavior with AI. Then they taught tiny robots how to do the honeybee dance. Using these dancing machines, the scientists were able to order the honeybees to stop moving, and to communicate where to fly to collect a specific nectar. In addition to the possibility of speaking with animals, the research could also be used to create a form of healing for animals and plants. That’s to say, in the near future, scientists might be able to get coral to grow in certain areas by playing “healthy reef” sounds, which could help to heal some of the damage we have caused.
Now, Digital Technology provides a new way for humans to listen to the vivid sounds all around us. The dream of allowing humans to socialize with different animals and plants throughout the nature is being on its way.
1. According to the passage, now people can use Digital Technology to ________.| A．see coral’s ears | B．listen to the sounds of trees |

A kind of little cars may take the place of（代替）today’s big ones. The car is as small as a bike but can carry two people in it. If everyone drives such cars in the future，there will be less pollution（污染）in the air. There will also be more space in cities，and the streets will have more space for people to walk.
The little cars will be cheap. These little cars can go only 65 kilometers an hour，so driving will be safer, too. The cars will be fine for getting around the city，but they will not be useful for a long trip. This kind of cars can save a lot of gasoline（汽油）.They will go 450 kilometers before needing to stop for more gasoline.
If big cars are still used along with the small ones，two kinds of roads will be needed in the future. One will be needed for the big, fast cars and the other will be needed for the smaller, slower ones.

Have you ever wanted to grow your own food inside your home? Scientists in Finland have developed a device(设备) that may do just that.
Unlike a usual vegetable garden, it doesn’t need soil. But, the small device, called the Cell Pod, grows plant cells which are safe to eat in the home.
Lauri Reuter, a biologist, says that instead of using the complete plant as food, scientists take only a small part of it–cells–and grow them in a bio-reactor(生物反应器). These plants have much of the same nutritional(营养的) value that a real plant has. The plant cells which are safe to eat, once fully grown, do not look very good. The Finnish researchers say they also need to improve the taste. However, the Cell Pod can provide important things that help your body to be healthy.
Lauri Reuter adds that the new technology will not be instead of fields for growing fruits and vegetables. However, the device could help save natural resources. All you would need to do is add the seed culture(培养物) to the device, give it water, sit back and then wait. The machine does the rest of the work.
The researchers hope to have a form of the Cell Pod on the market in the next ten years.

【推荐1】Sunshine, beaches and coconuts (椰子)—these are why people usually go to Hainan. But more than a paradise (天堂) for travelers and foodies, it’s also a wonderland of plants and animals.
Hainan Tropical Rainforest National Park, in the south-central part of Hainan Island, has the most and well-kept tropical rainforests (热带雨林) in China. President Xi Jinping visited it in April.
The national park covers 4,269 square kilometers, or one-seventh of the island. More than 95 percent of the park is virgin (原始状态的) forest and is home to 3,653 species of vascular plants (维管植物) and 540 species of terrestrial vertebrates (陆生脊椎动物).
The park is the only habitat (栖息地) of the world’s most endangered primate (灵长类动物)—the Hainan gibbon (长臂猿). It’s an uncommon species (种类). They look like monkeys, but have no tails. They live in the trees their whole lifetimes. Every morning, they whistle loudly to mark their territory (领地). They eat fruits and leaves from more than 130 plants. The number of Hainan gibbons has increased from fewer than 10 in the 1980 s to 36 in 2022. This shows China’s achievements in environmental protection.
Not just a sweet home to animals, the park is a “live museum” of amazing plants. More than 400 kinds of plants grow only in Hainan. Cycas hainanensis (海南苏铁) is a wild plant native to the island. With feather-like leaves, this plant can live to be 200 years old. If it lives in the Yangtze River Basin and North China, it grows almost without flowers or fruit. But in Hainan, cycas hainanensis plants over 10 years old blossom (开花) and bear fruit almost every year, thanks to the warm and humid (湿润的) weather.
With so many plants and animals, the biodiversity index (生物多样性指数) of the park—a number to rate species diversity—is as high as 6.28. It is comparable (可比较的) to the Amazon rainforest in Brazil. That’s why people call the park a treasure for both China and the world.
1. Paragraph 3 is mainly about ________.| A．an introduction to the park | B．the views of the park |
| C．the news of the park’s opening | D．details of rare plants and animals |
| A．It is a monkey without a tail. | B．Its voice sounds like a crying baby. |
| C．It lives on plants and birds. | D．It is a species only found in Hainan. |

| C．lives better in warm and humid weather | D．first blossoms when it is 10 years old. |
| A．We must start to do something for rare species. |
| B．Human activities will do harm to the rainforest. |
| C．China has done a great job in protecting the rainforest. |
| D．We should compare our rainforest with the Amazon rainforest. |
Have you ever seen such a big tree in front of a temple? Not everyone can recognize this as an olive tree, but most of us understand the meaning of the phrase “extending an olive branch,” long known as a gesture of peace and friendship.
That idea of peace, friendship, and wisdom is at the heart of UNESCO’s World Olive Tree Day, created in 2019 and celebrated every November 26. The purpose of the day is to bring attention to the resolution of fights all over the world and to the protection of the olive tree itself, like this one standing in front of the Temple in Italy. The temple was built on what is now the south shore of Sicily, a small island in Italy, around 440 BC (公元前). Olive trees are native to the coastal areas of the Mediterranean (地中海) and are planted today in places with similar climates, like parts of California and Israel. About 90% of collected olives are used to make olive oil, the perfect ingredient in Mediterranean cooking.
The planting of olives is about as old as human civilization (文明) itself. ▲ , usually no more than 30 feet, they live a very long time. One of the oldest known trees in the world is believed to be 3,350 years old. Many live for more than a thousand years, their trunks growing thick and curled, and their branches bearing fruit century after century. As civilizations rise and fall around them, these trees remain hardy and strong.
1. The underlined phrase “extending an olive branch” in the first paragraph means “________”.| A．延展橄榄枝 | B．伸出橄榄枝 |
| C．拥抱和平鸽 | D．放飞和平鸽 |
| A．people could celebrate the World Olive Day on November 26, 2018 |
| B．the temple on the south shore of Sicily is more than 2500 years old |
| C．olive trees can’t be planted today in places with similar climates |
| D．about 90% of collected olives are used to make olive oil |
| A．Although olive trees do not grow very tall |
| B．Although olive trees are very easy to plant |
| C．Although olive trees grow for a long time |

【推荐3】There are too many mysteries in the world that we haven’t discovered yet. Some of them are hidden in the places which are impossible to find. Others remain unsolved even up to this day. In s small town of Gryfino in Poland lies one of the world’s mysteries that have been known — a small group of pine trees (松树). These trees look strange in shape. From the lowest place, these trees grow with a 90° bend (弯曲) to the north, but then go back to grow straight up into the sky.
According to scientists, the pine trees there were planted many years ago. Though they are strange in shape, these trees are generally healthy. Most of them are very tall. Some even grow to nearly 15.24 meters. That’s about the height of a five-story building. There are many guesses about the mystery of the trees in the forest. Some guess that the special gravity (重力) in this area has caused the trees to bend to the north. But it seems that this guess isn’t proper, because gravity only pulls things down and doesn’t make them bend. Others guess that the heavy snow in the area weighs down the trees as they are small. However, if that is the case, how would they explain the fact that the other trees in this area are not the same?
The most possible explanation is that local farmers shaped the trees when planting them. In the past, it was common for farmers to shape their plants for special purposes. However, that is only one of the guesses from people. The secret behind the trees is still waiting for us to discover.
1. Which of the following is TRUE about the pine trees in Poland?| A．They look small in size. |
| B．They don’t grow so healthily. |
| C．They grow with a 90° bend to the south |
| D．They may be as tall as a five-story building. |
| A．Unbelievable. | B．Correct. | C．Interesting. | D．Valuable. |
